Before we can start to make changes, we have to decide exactly what we want to change or what we want to change first. We might want to eliminate animal products or cut down on them. We might want to stop eating refined processed foods and start eating more whole, fresh, plant-based foods. We might want to lose some weight. We might want to stop smoking or drinking alcohol or overeating. We might want to take up running or yoga or Pilates or train to run a half or full marathon.
